5mm round is a type of ammunition in Fallout.

Background[]

This section is transcluded from 5mm round. To change it, please edit the transcluded page.

A high velocity round designed for assault rifles, the intermediate 5mm M134 cartridge[1] has been replaced by the more powerful 5.56mm round in assault rifles.[2] However, it found a new life as linked, belt fed ammunition for man-portable miniguns on the battlefield, specifically the M134 cartridge and is stored in downscaled ammo boxes designed for the 7.62x51mm NATO cartridge in Fallout 4 and Fallout 76.[3] It has also been retained as the ammunition of choice for certain models of assault rifle and paratrooper assault carbines, due to its light weight and portability.[4]

Characteristics[]

A decent round, though it is outclassed by 12 gauge shells and .223 FMJ rounds, since weapons chambered for these ammunition types come into play at around the same time.

Variants[]

There are two variants of 5mm ammunition, however, ammunition modifiers are not applied properly which makes the 5mm equal to any other kind of ammunition, and both JHP and AP versions functionally identical.

  • 5mm AP (A brick of small caliber ammunition. 5mm armor piercing.)
  • 5mm JHP (A brick of small, lightweight ammunition. Caliber: 5mm, jacketed hollow-point.)
